PLEASE either make vendors searchable or sort them logically!

It drives me absolutely bonkers. It should NOT take 15 minutes of scrolling line by line back and forth to trying to find the wand you need to buy the wand you need to buy the wand you want. Either put them in order, grouped together, or make the vendors searchable. The sorting of the vendors' bags really don't make any sense. It appears to be by price, but that method makes it pretty near impossible to easily find the gear (or ingredients) you actually need when there's several screens worth of sets to scroll through.

Personally I'd prefer tabs by item type(i.e. armor, weapons, essences, costume, etc.), similar to the Buy Back tab currently at bottom of vendor window, but above instead. Get rid of the scrollbar all together and allow for resizing the window.
